DOOR-OPENER.

SPECIFICATION forming part of Letters Patent No. 749,339, dated January12, 1904. l l Application filed September 14, 1903- Serial No. 173,151.(No model.)

T0 at whom may concern:

Be it known that I, GEORGE L. THEIGE, a

by, in the county of Vernon and State of VVisconsin, have inventedcertain new and useful Improvements in Door-Openers, of which thefollowing is a specification.

This invention provides a mechanical device for simultaneously openingor closing a plurality of doors, shutters, or like closing means.

The device embodied in the invention is especially adapted. for use inconnection with tobacco-curing barns, which are, as is commonly known,provided with a number of doors upon all sides whichwhen open permit athorough ventilation of the barn and facilitate thedrying of the tobaccowhich is disposed therein.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction and the means foreffecting the result reference is to be had to the following descriptionand drawings hereto attached.

While the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which- Figure1 is a perspective view of the dooropener device in applied position.Fig. 2 is a top plan view of the opener device disposed also in anoperative position and showing its relative disposal when the doors arethrown open. Fig. 3 is an enlarged perspective view of the operating-barcarrying the arms. Fig. 4 is a transverse sectional view through theoperating mechanism and the adjacent parts to which the same isattached. Fig. 5 is a detail view showing most clearly the exact form ofmanner readily seen. It will be understood that the doors may beprovided in any number and that the operating-bar 3, by which the saiddoors are simultaneously thrown open or shut, may be provided with meansfor connecting the same to such doors. Each of the respective doors 2 isprovided with brackets 4:, which are suitably secured to the doors bysubstantial fastening means.

The operating means comprises a longitudinal bar 3, before mentioned,and arms 5, projected from the aforesaid bar and adjustably mounted formovement thereon. The bar 3 may be of any length, and the arms 5, beingadapted for adjustment withreference to the bar 3, permit the use of thelatter in connection with doors which maybe disposed at intervals ofdifferent lengths and also admit of ready removal of the arms fromcertain doors should it be desired that the same be not operated alongwith the doors which remain connected to the bar. The arms 5 are ofpeculiar form, each comprising a body 5, of approximately U shape,having spaced clamp members 5 laterally projected therefrom. The members5 embrace the operating-bar 3 upon opposite sides, and openings aredisposed upon the ends of the members 5 to receive a clamp element 7, bywhich the members 5 are caused to firmly clamp the operating-bar. Byloosening the clamp element 7 each arm 5 may be given a longitudinalmovement upon the operating-bar 3 to properly adjust the same withreference to the door to which it will be attached. Obviously byentirely removing the clamp element 7 the arms 5 may likewise be removedfrom the operating bar. Corresponding ends of the U-shaped bodies 5 ofthe several arms 5 are received between the brackets 4, projected-fromthe doors 2 and pivotally secured in such a position by means of atransverse pin or ,the like. By the provision of U-shaped parts 5 uponthe arms 5 the operating-bar 3 is rigidly maintained in positionrelative to the doors, and at the same time the exact form of these armspermits of throwing open of the doors, since the line of draft is in alateral direction relative to the brackets 4E. Handles 8 are provided ateach end of the operating means, so that the doors 2 may be thrown openby an operator standing at either end of the operating-bar by a pull orpush movement of the said bar.

In order that the doors 2 may be held open at different positions, abracket 9, projected from the building or wall upon which the doors aredisposed, is utilized, the said bracket being provided with spacedmembers disposed upon opposite sides of the operating-bar 3. Openings inthe spaced members of the bracket 9 receive a pin 10, which is alsoadaptedto pass through a plurality of spaced openings 11 upon theoperating-bar 3, so that the position of the bar 3 may be fixed atdifferent points in its longitudinal movement.

Having thus described the invention, What is claimed as new is- 1. Incombination with a plurality ofdoors, an operating-bar disposed adjacentthereto, approximately U-shaped arms projected from the saidoperating-bar and having corresponding end portions secured to the door.

2. In a device of the class described, the combination with a pluralityof doors, an operating-bar disposed adjacent the said doors, andU-shaped arms adjustably mounted upon the said operating-bar andpivotally connected to the said doors.

3. In adevice of the class described, the combination with a pluralityof hinged doors, an operating-bar disposed adjacent the said doors, armsprovided with spaced members to embrace the operating-bar connected tothe doors, means for clamping the spaced members of the arms about theoperating-bar.

4. In a device of the class described, the combination with a pluralityof hinged doors,

an operating-bar disposed adjacent the said doors, arms removablysecured to the operating-bar and pivotally connected to the doors, andmeans for co-operation with the operating-bar to fix the position of thesame at different adjustments.

5. In a device of the class described, the combination with a pluralityof doors, brackets projected from the doors, an operatingbar disposedadjacent the doors, arms secured to the operating-bar aforesaid, saidarms comprising a U-shaped body and laterally-spaced members, the latteradapted to. embrace the operating bar upon opposite sides, clamp meansdisposed upon the lateral members of the arms aforesaid to cause clampaction of the said members upon the operating-bar.

6. In a device of the class described, the combination with a pluralityof doors, brackets projected therefrom, an operating-bar disposedadjacent the doors, U-shaped arms adjustably mounted upon theoperating-bar and pivotally secured to the bracket upon the doors, theoperating-bar being provided with a plurality of openings therein, afixed projection disposed adjacent the operating-bar, and a pin adaptedto be passed through the said projection and any selected opening in theoperating-bar to thereby adjustably fix the position thereof.

In testimony whereof I afiix my signature in presence of two wltnesses.

GEORGE L. THEIGE.
